Procurement Notes

Verify the specific suffix 'KD' against official Analog Devices documentation to confirm the exact package type and temperature grade. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the procurement source provides valid traceability data. Cross-reference the manufacturer part number with the distributor catalog to avoid substitution errors. Validate that the received component matches the specified 16-CDIP form factor before integration.

Selection Notes

Select this component when dual-channel linear multiplication or division is required within a single package. Consider the 400 kHz bandwidth limit for high-speed signal applications. Evaluate the ±4.5V to ±18V supply requirement against available power rails. The 16-CDIP package necessitates through-hole mounting technology. Verify that the -55°C to +125°C temperature range meets the operational environment requirements. Compare power consumption of 10.2 mA against system budget constraints.
